METALLIC BRUSH.

SPECIFICATION forming part of Letters Patent No. 396,289, dated January 15, 1889.

Application filed December 21, 1887. Serial No. 258,598. (No model.)

To aZZ whom it may concern.-

Be it known that I, STEPHEN PORTER, a citizen of the United States, residing at Boston, in the county of Suffolk and State of Massachusetts,have invented certain new and useful Improvements in Metallic Brushes; and I do hereby declare the following to be a full, clear, and exact description of the inventiomsuch as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

This invention relates to improvements in metallic brushes, so called, in which small wires secured to a flexible piece of material or backing are substituted for animal bristles. This backin g, having been studded with these small wires, is then attached to the back of the brush by tacks or other analogous fastening implements.

To conceal the heads of the latter and prevent the hair from catching or becoming entangled therewith, as well as to cover the projecting portion of the flexible material containing the fastening-tacks, and likewise produce an ornate ettect, I have disposed exteriorly of and about the wires a continuous met allic ring, plated or otherwise embellished.

My invention relates to the manufacture and peculiar construction of said metallic ring, by which it is readily and easily secured to the back of a brush in such manner as to present a finished and ornamental appearance to the brush as an entirety.

The drawings represent, in Figure 1, a per spective view of a metallic ring embodying my invention. Fig. 2 is a vertical cross-section of a metallic brush with the ring in its final position. Fig. is aside elevation of the back of a brush, showing the fastening attachments secured thereto which engage the ring to hold the latter in place. Fig. 4 represents a modified form in the fastening arrangement.

This invention may be considered as relating to and as an improvement upon a previous invention of mine, (for which I have made application jointly with G. L. Hergertfor Letters Patent, filed September 2, 1887, Se-

rial No. 248,616,) which pertains to metallic brushes in which a continuous integral metallic ring provided with a series of fasteningpoints, also integral therewith, was arranged to fit exteriorly about the wire bristles and cover the fastening implements which are employed to secure upon the back of the brush the flexible material in which said wires are massed. The object of my invention is to cheapen the construction and enable the metallic band to be fastened more quickly in position in the process of manufacture of this class of brushes.

In the drawings, 2 represents the back of a brush made of any suitable material, and to which is secured a piece of flexible or yielding material, 3, in which are inserted and closely massed together a series of small headed wires, 4. A small portion of this elas- 7o tic material extends beyond the mass ofwires and serves to receive the fastening implements, as tacks 5, which are used to unite said material containing the wires to the back of the brush. To retain said fastening-tacks in place, prevent their escape, and at the same time produce a smooth and neat appearance, I have superimposed extcriorly about the mass of wires and over the fastening-tacks 5 a continuous integral metallic ring or band, 6. This ring is struck up from some thin blank sheet of metal, and approximates in shape to the general shape of the mass of wires which it surrounds. In crosssection this ring is cupped or hollow, being concavoconvex, the concave portion being adapted to receive the edge of the flexible material, over which it extends and upon which it rests, thus covering the fasteningtacks 5. Moreover, the rounded or convex ex- 0 terior surface presents a more ornamental and finished appearance to the article as an entirety. In the process of striking up this continuous integral ring from a blank sheet of metal, I have also formed integral therewith a series of fastening spurs or lips, 7. The latter are continuations ofthat part of the ring which is contiguous to the back of the brush; but in lieu of being aligned therewith, as in my previous invention above re- :00 ferred to, they are bent at right angles inwardly to the ring at their point of junction with the latter. To attach this ring to the back of the brush, I have inserted in the back of the brush a series of fastening staples or eyes, 8, preferably so located that when the ring rests in position on the back of the brush said eyes shall bear against the ring. These fastening devices may be of various shapes and forms, but their function is to engage with the fastening lips or spurs formed integrally on the ring. Furthermore, these fastening devices 8 are positioned on the brush to coincide with the position of the holding-lips 7 on the ring.

In the operation of securing the metallic ring to the back of a brush said ring is first adjusted over the mass of bristles, and the series of lips 7 upon one side are then ongaged with the corresponding series of eyes, 8, the ring being held in an oblique position to the back of the brush. The raised side of the ring is then brought down until almost parallel with the back, then by pressure or otherwise it is forcibly sprung outwardly or expanded until the lips '7 are enabled to enter and engage the fastening devices 8, adapted to co-operate with them. As soon as the pressure is removed the inherent elasticity of the metal composing the ring restores the latter to its former proportions, and the lips '7 are held in positive engagement with the fastening devices 8 on the back of the brush. Thus it will be seen that the eX- pense of making the ring is very small, and when the fastening devices, readily inserted mechanically in the back of the brush, are in place the ring can be attached very quickly and expeditiously. Moreover, after being properly positioned the fastening-tacl is 5 are prevented from working loose, dropping out, and escaping.

\Vhat I claim is 1. In metallic brushes, a continuous integral metallic ring struck from a blank and provided with a series of fastening-lips, also integral therewith, arranged around its lower edge or contour, said lips being disposed transversely of said edge, substantially as and for the purposes described.

2. In metallic brushes composed of a back portion and a flexible piece of material studded with a massed series of wires attached thereto, a series of fastening devices inserted in said back, combined with a metallic ring having transversely-(1isposed fasteniiigdips adapted to engage the fastenin on the brush, substantially as set forth.

In metallic brushes, the combination,

with the back 2 and the fastenings 8, a massed series of wires, 4, and the flexible material 3 with its fasteni n 5,0t' the integral continuous metallic ring 6, concavo-convex in cross-section, adapted to rest upon the back 2 and overlap the projecting edge of the material 3, and the series of holding-lips 7, integral with and bent transversely of said ring, all co-operating as herein set forth and described.

In testimony whereof I at'fix my signature in presence of two witnesses.
